FIELD: instrument making.
SUBSTANCE: invention relates to portable device for field servicing with improved diagnostic functions. Result is achieved by that controller can receive context information with respect to current operation of field servicing and pre-load at least one resource in relation to next step of performing field operations. Controller can receive emergency information of process through a wireless communication module and safety information of field device via module of technological communication and provide on display device an indication of emergency information process and warning information of field device. Controller can execute a sequence of operations of maintenance of field device on field device in response to a signal from a user input device. Controller can receive information describing current state, in response to a signal from a user input device.
EFFECT: technical result consists in improvement of efficiency of diagnostic functions.
